Rational design of graphitic-inorganic Bi-layer artificial SEI for stable lithium metal anode

The bi-layer artificial solid electrolyte interphase for lithium metal anode, composed of covalent graphitic materials and inorganic components, is rationally designed. The graphitic layers possess high mechanical strength and stiffness which can effectively release the stress produced by the non-uniform growth of lithium while the inorganic layers can prevent the graphitic layers from corroding by electrolyte and stably cover on the lithium metal surface.216
